Patent CA-2025059-A1 (CA)
IPC: F01L1/344
Filed: 1990-09-11
Abstract: CAMSHAFT PHASING DRIVE WITH WEDGE ACTUATORS Abstract of the Disclosure A phase adjuster for engine camshafts and the like includes in a preferred embodiment a sprocket driving a camshaft attached hub through paired wedge packs that transfer torque and maintain a lash free connection.  A plunger actuated by engine oil pressure and coacting drive springs axially move alternate active wedges to oppositely vary the arcuate lengths of the wedge packs and thereby change the phase angle between the sprocket and camshaft.  A three way valve shuts off pressure oil flow except when needed to advance the plunger, thus minimizing oil flow requirements.

Title: Container for supplying liquid agricultural treatment agents in a closed application system
Inventor: REED DAVID A
IPC: B65D23/10
Filed: 1990-12-24
Abstract: 31?27 CONTAINER FOR SUPPLYING AGRICULTURAL TREATMENT    AGENTS IN A CLOSED APPLICATION SYSTEM               ABSTRACT OF THE DISCLOSURE       The present invention provides a container for use in a closed application system for liquid or granular agricultural treatment agents. The agent is introduced into the container through an inlet opening on the upper surface of the container. Thereafter, a valve is removably mounted to seal the inlet opening and prevent inadvertent discharge of the liquid from the container. Hand grips are provided to manipulate the container, and the container is configured so that it nested or stacked on other similar containers having valves extending from the respective inlet openings when the containers are transported in an upright position. The handgrips are also employed to mount the containers in an inverted position in agricultural application equipment. Empty containers may be trans-ported back to a supply station for refilling with the valves of the respective containers still mounted in the inlet openings to seal the openings and prevent inadvertent discharge or leakage of residue liquid or granular treatment agents still remaining in the containers. The reusable containers enable the agri-cultural treatment agents to be transported between a supply station and application equipment without any direction exposure to the user.

Title: Cleaning of articles
Inventor: WEEMES GEOFFREY C
IPC: C23G5/02
Filed: 1991-09-13
Abstract: ABSTRACT CLEANING OF ARTICLES            Articles contaminated with soil etc are cleaned by contact with a non-chlorinated organic solvent having a relatively low flashpoint, such contact being made at a temperature below such flashpoint. The articles are then contacted with an aqueous rinsing medium at a temperature below the flashpoint of the solvent. These steps lead to contamination of the solvent and the rinsing medium and to free them of the contaminants, which are substantially non-volatile, the contaminated solvent and rinsing medium are fed to a steam distillation unit in which the rinsing medium and solvent are co-distilled at a temperature above the flashpoint of the solvent. The steam distillation is carried out in a fire hazard containment zone in which oxygen is substantially excluded during normal operation of the steam distillation unit by the water/solvent vapour generated, and during commencement and cessation phases of steam distillation by the generation of an inert gaseous fluid.

Abstract: This invention relates to improvements and modifications to a rock crusher. The rock crusher has at least two jaws the jaws being driven at different ends to each other. The non-driven end of at least one jaw is sufficiently free to allow vertical movement of that jaw with respect to the other jaw. This vertical movement imparts a grinding action in addition to the crushing action of the rock crusher. This removes the problems which can occur with wadding and can produce a very fine ground rock.

Title: Fastener with internal threaded installation means
Inventor: BATCHELOR JOHN S
IPC: F16B31/02
Filed: 1991-12-10
Abstract: ABSTRACT OF THE INVENTION         A fastener for use in fatigue resistant structures such as aircraft wings.  The fastener is installed into inter-ference fit by tool engagement in a tapped hole coaxial with the threaded end of the pin, at the threaded end of the fastener pin.  The tapped hole is engaged by a hardened mandrel which is detachably threaded into the threaded hole in the pin.  The mandrel has an extending tail end which may be gripped by a pulling tool after the threaded end of the pin is partially inserted into the workpiece with the mandrel extending through the workpiece.  The tail end of the mandrel is engaged by a pulling tool that can be manually or power actuated to pull the interference fit shank into the structure workpiece to produce a fatigue resistant interference between the pin shank diameter and the workpiece hole diameter.  The process results in fatigue-proofing the joint and produces the benefit of holding the pin from rotation when a threaded collar or nut is applied to the threaded end of the pin to complete the joint, installation being done without exertion of percussion forces.

Title: Envelope flap moistener and sealer
Inventor: DEFIGUERIDO CARLOS L
IPC: B43M5/04
Filed: 1991-12-11
Abstract: ABSTRACT OF THE DISCLOSURE       Modular apparatus is disclosed for moistening and sealing an envelope flap.  The apparatus comprises a base, in which a moistener is disposed and in which part of a transporter for moving an envelope to and past the moistener is also disposed.  A cover in which the remaining portion of the transporter is dis-posed is pivoted to the base so that the cover may be pivoted open to expose the envelope path and the parts of the transporter in the base and in the cover.  A pair of sealing rollers, one mounted to the base and the other to the cover, are disposed in the same module as the moistener downstream from the moistener.          Providing part of the transporter in the base and part in the cover, and pivotally mounting the cover to base enables one to quickly gain access to the envelope path simply by unlatching the cover and pivoting it away from the base.  This enables an opera-tor to quickly gain access to the envelope path to remove a jammed envelope.     MD11.pit378.001(C-755)

Abstract: Multimedia bioreactor and periodic washing method therefor ABSTRACT OF THE DISCLOSURE           The bioreactor  consists  of  a basin which holds  two superimposed layers of biomedia supported by a false floor.  The waste liquid is poured over the top of the bioreactor, and seeps through the layers of media and into the nozzles mounted on the false floor.   The upper layer of media consists of low density buoyant material, the lower layer of media consists of  non-buoyant material.  The upper media layer performs mainly reduction of the organic load in the waste water, while the lower layer completes the biological degradation with in addition retaining the solids in suspension in the waste water.  Water and compressed air are fed from under the false floor, to enable periodic backwash cleaning of the bioreactor, so as to remove the accumulation of retained material.  The extraction of the dirt-loaded backwash water is done by overflowing, or under siphon action.

Abstract: Synthetic hypocalcemic peptides which are similar in biological properties to native calcitonins as clinically useful agents. The peptides comprise analogues of native calcitonins having amino acid substitutions and deletions which act to improve potency, prolong duration of the hormonal effect, enhance receptor binding, and increase oral or nasal bioavailability. The calcitonin peptide analogues are less expensive and more easily synthesized than native calcitonins, and have improved resistance to inactivation or degradation. Methods are provided for the synthesis of these peptides. Also disclosed are novel cyclic peptides, including calcitonin, having increased stability with respect to proteolysis.  Methods for the synthesis of these peptides are provided, comprising converting disulfide cyclic peptides and proteins to enzymatically and chemically stable cyclic peptide structures by the replacement of cysteine residues with dicarboxylic acids and diamino acids. The method is applicable to various naturally occurring peptides, their synthetic analogues or derivatives, and proteins.
